摘要: 利用矩量法导出Vlasov辐射器端口处各种模式模系数（振幅）的计算方法，并利用此方法通过数值计算研究了斜切形Vlasov辐射器的反射特性，得到了辐射器端口反射系数和斜切角度及直径波长比之间的关系。结果表明斜切形辐射器具有很小的反射系数，并从反射特性上为辐射器结构参数的选择提供了依据。Abstract: This paper presents a calculation method of the mode coefficient (amplitude) on Vlasov radiator aperture by Method of Moments (MoM), and the reflective characteristics of bevel-cut radiator are studied through this method. The relations of the reflectivity to bevel-cut angle and diameter-wavelength ratio are obtained, which indicate that the reflectivity of the radiator is very small. The results are helpful for the design of the radiator.
